message: "string.substitute could not find key \"loadingState\" in template" esri javascript 3.23

Question

I am trying to add a measure widget from the esri samples and I get the following error.

I am using boostrap.css and I am wondering if this has an effect on widget loading.

<div class="container-fluid" data-dojo-type="dijit/layout/BorderContainer" data-dojo-props="design:'headline',gutters:false">

I am also wondering if these tags conflict with each other. I have trouble getting widgets to show in my map div.

<div id="map" data-dojo-type="dijit/layout/ContentPane" class="is">

I toggle the classes to change the page width and show a side bar menu.

I saw a similar question with no answer.

Answer 1

The error message of string.substitute could not find key "loadingState" in template actually refers to a missing variable in the function that is using the "ContentPane" widget.

Take this method that will attempt to load the "dijit/layout/ContentPane" using the parser:

require(["dojo/parser", "dijit/layout/ContentPane", "dojo/domReady!"], function (parser) { parser.parse(); });

SOLUTION, add a variable for the missing "loadingState":

require(["dojo/parser", "dijit/layout/ContentPane", "dojo/domReady!"], function (parser) { loadingState = "Loading"; parser.parse(); });
